2020 LowDown Showdown Winner – Team Aequitas

SIGN UP NOW

Each year of the LDSd competition, we ask participating teams to take on a new challenge in building performance analysis. For 2021 the competition will ask teams to expand their comfort zone and take on the challenges of a tropical climate with particular challenges for resiliency and “near net zero” design. The competition will also require teams to use their creativity to develop schemes for engagement of the building & its occupants with the community.

The 2021 LDSd model building will be located in Puerto Rico. Participating Teams will design a 75,000 sf, residential care center located at a site on the island to be chosen by each team. The building will contain residences, offices, amenities and clinical spaces.

Here’s your chance to join an integrated team that will compete for fun and prizes in the annual LowDown Showdown modeling competition. Sign your team up today or sign up as an individual participant and we will put you on a team! Bring your imagination and analytical skills to the party and create the prototype building of the future!
